  • Effects of Aggregate Properties on Concrete - Size, Grading

    Effect of Grading. Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability.

  • How Coarse Aggregate Affects Mix Design of Concrete?

    As far as shape is concerned, rounded shape aggregate provides economical mix design for normal strength concrete. However, angular coarse aggregate is desired in the case of high strength concrete. This possibility of segregation is minimized if coarser aggregate is properly graded. This explains how important is good grading for concrete mix ...
